Resizing Images within a WrapPanel in C#

Question

I'm trying to fill a WrapPanel dynamically with Images,
The Window that contains the WrapPanel is resizable, and i would like to
make the images within the wrappanel resize when they got more space.

My problem is that i want the images to resize if i add more to the wrappanel.

For example:
If there is only ONE image, it should take all the space it can,
but if i add another, they should both be resized, so that both only take half the space.
Both images should grow if i resize the Window and make it bigger, but they should also shrink if i shrink the Window.

I'm sorry for my terrible english-
I hope i could explain my problem.

My Code:

C#

string path = s;
                   BitmapImage bit = new BitmapImage();
                   Uri ur = new Uri(path);
                   bit.BeginInit();
                   bit.UriSource = ur;
                   bit.EndInit();

                   System.Windows.Controls.Image tempimage = new System.Windows.Controls.Image();
                   tempimage.Source = bit;


                  tempimage.Stretch = Stretch.Uniform;

                  //### THESE DID NOT WORK
                  // tempimage.Height = Double.NaN;
                  //tempimage.Width = Double.NaN;
                   //wrapPanel1.ItemHeight = Double.NaN;
                   //wrapPanel1.ItemWidth = Double.NaN;
                   //###


                   wrapPanel1.Children.Add(tempimage);

Can anybody help me?

Hi Feverbird,

Just use UniformGrid instead, for example:

MainWindow.cs:

XML

<Window x:Class="WpfApplication4.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <DockPanel LastChildFill="True">
        <Border DockPanel.Dock="Top">
            <Button Width="100" Content="Add" Click="Button_Click" />
        </Border>
        <UniformGrid x:Name="panel"  />
    </DockPanel>
</Window>

Code Behind:

C#

/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        var image = new BitmapImage(new Uri("Choice_toxicity_icon.png", UriKind.RelativeOrAbsolute));

        panel.Children.Add(new Image() { Source = image , Stretch = Stretch.Fill});
    } 
}

Best Regards,

Shai
